I'm a huge fan of reverb. Picked up a kemper - absolutely love it! Delay is nice - happy to drop my Strymon Timeline, but I find the reverbs lacking big time compared to my BigSky.
has anyone got any advice other than "run it in the effects loop". Ideally I'd love to drop all my pedals (as my friends using the kemper have done) and just run the kemper remote by itself, but feel id be losing a lot... Advice 
I'm running two Eventide H9s in the loop of mine. 
If you use a combination of delay and reverb, and tinker with the various options for each of them like Delay/Reverb Mix or whatever it's called, you can get some "better" reverb sounds than what the reverb effect will do by itself.
However, the Kemper definitely falls short for some of the more unique delay/reverb effects people seem to want, like "Shimmer".
Have you checked all the options, types of reverb and presets? There are some great sounds available IMO
Look into the MAB profiles. There's also been some rumors that we may be seeing some updates from NAMM that could affect reverbs, but just speculation based on some videos Kemper posted on their Facebook site. Check it out.
Seconded that NAMM might produce some quality reverbs. That said, the Kemper's reverbs are moderately OK, but I mainly play post-rock/ambient/worship stuff, and often without a keyboardist. In those situations, I need LONG and BIG reverbs. The "ambient" reverb type just doesn't sound good on the Kemper. And there's no spring verb either.
MAB's stuff is good, but it still just doesn't get what I need.
IMO, both the delays and the reverbs are lacking, but for popular uses of delay and reverb, they are sufficient. I run a Timeline and a BigSky in my FX loop, and they work great.
Same here. Just got a great deal on an H9 Max on eBay.
